    I run the square to spreadbore adaptor. Anyone who does this, be sure the check to see if the supplied screws go into the intake far enough to provide the proper clamping force. I found two screws that bottomed out before providing just enough clamping force on the adapter itself.

    Replacing an older 1406 with a 1902 AVS2 for my jeep's Chevy 383 mild cam, operate 4500 rpm and below, will begin with 12-13 degrees of timing, but a real torque monster, love it.
    Attempting to squeeze a little more fuel mileage from "old blue". We'll see, not expecting much change to fuel mileage, to be honest, but wanted to check out the newer AVS2 and it's upgrades.
    Will be adding an AFR soon as well.

      You could see some MPG from that change. For what you’re doing, the 500 sounds like it will be sized better. I’m sure you’ll have much better throttle response. Once you get it all together and tuned, please tell me how it’s responding! The GMC has tried to kill me over the past couple weeks. 😂 Still have a bunch to do to get it back on the road!

    I'm in the process of optimizing an AVS2 650 on a 302 ford, 1969 mustang, C4, 3500 stall, 3.55 gears with an A/F meter. It has a 10:1 compression, TFS TW heads, cam is 224/232 dur at 0.050, Perf RPM intake, 1 5/8 headers, dual 2.5" exhaust, mechanical pump at 5 PSI. Idle is ~12" of vacuum at ~850 RPM, using pink springs(7"), accel pump is in the middle slot, timing is set to 16-32 degrees all in by 3000, 8 degrees of vac. advance. The rods were changed to 73-42 (2 stages leaner on cruise and 1 stage leaner on power). Idle & Cruise A/F is 13.5-14.5 and power is around 11-12. When letting off on the throttle to stop the mixture goes lean and on a longer downhill stretch it will hit 17:1. The vacuum goes up around 20" when off the throttle so the rods will be right down and the timing has the max advance. With the 70-37 rod the A/F doesn't go above 16, when off the throttle, but when in cruise mode the A/F goes into the 12s and power mode goes into the 10s. Is a 17:1 A/F mixture an issue or is it fine cause there is no load?

      @@MuscleCarSolutions That helps, keeping the A/F in the 15 range when completely off the throttle. I have 2 additional issues, on first tip in there is a hesitation with the A/F going up to ~16.5 and when using a lot of throttle the A/F goes down to around 10. For the hesitation changing the step up springs from orange to pink to silver and putting the accelerator pump in the top hole has reduced the effect but hasn't eliminated it. Is the next step to add a larger accelerator pump jet? or larger accelerator pump? Does the Air valve secondary matter at this low of RPM? I have reduced tension on the air valve due to the rich condition when leaning on the throttle. For the rich condition, is there an easy way to know if the carb needs smaller secondary jets vs adjusting the air valve or both? something else? Thank you!

    Been a subscriber for a while and finally have an issue I can't find an answer to. I swapped from a 2bbl to a 1406 and now it wont rev past 3000. Throttle isn't binding and cable is correct length. Regulator shows 5.5 lbs consistent up to the 3000. I know it's a longshot, but any ideas? The only change I made was the carb, and all I've done to the carb is basic set up.

      Never. If they are that worn, it’s cheaper to huck it and get another core or carb. Way too messy to take one apart at that level, machine it, size it and attempt to put it back together. For the time you’d have invested, it’s well worth looking for another one.

    Really enjoying the wealth of information and presentation style of your channel! Quick question if you have the time: why is my carburetor’d car hard to start after being driven and then sitting for ten minutes or so. I had a carb on my 1980 Z28 in high school and don’t remember this ever being a problem. Putting together an 87 Formula that had a carb on the 305 before I pulled it for a 350 and now I’m experiencing this issue. Thanks!

    • @MuscleCarSolutions
      @MuscleCarSolutions  Рік тому +1

      Ethanol! Doesn’t matter what flavor carburetor you have, the ethanol in the fuel is awful. I’m just a little above sea level and here ethanol boils around 175 degrees. The higher you go in elevation, the higher that number goes, but not by much. So when you drive for a few and hop out to get a coke or grab some lunch and come back 20 minutes later, the fuel has been sitting in the carb boiling. The hard starting is flooding of that fuel into the engine. I really appreciate you watching!

    Thanks for the video! I've got an unsolved problem. Just bought this truck with a 360 FE engine, a 2V intake manifold, an adapter, and a 4V Edelbrock carb. Truck has sat quite a bit and idles pretty crappy. If I put my hands over the carburetor and restrict the airflow some, the idle speeds up and smooths out. I'm thinking vacuum leak, but if so it's hard to find. We replaced the manifold-to-adapter and adapter-to-carb gaskets - no difference. I can disconnect the brake booster and hold my finger over the hose - no difference. We tried spraying carb cleaner in various spots, but the vapors would speed up the engine a little no matter where we sprayed. We didn't learn anything useful.
    Do you agree that it sounds like a vacuum leak? Or could it be something gummed up in the Edelbrock carb that sat too much? Thanks!

    • @MuscleCarSolutions
      @MuscleCarSolutions  11 місяців тому

      Yes, it’s a vacuum leak. Pretty common when using a spread bore adapter. There’s so many variants of carburetor and manifold from the factory it’s impossible to make an adapter for them all. So occasionally you’ll need another inexpensive plate to help seal it up. Edelbrock 2731 or 2732 should get you fixed up. The carburetor cleanliness is a separate issue.

    Is there a choke pulloff adjustment on the choke piston/housing on Edelbrock carbs? This would be similiar to an older holley where the choke will be completly closed after setting, but then immediately open partially when the engine has started and has vaccum, and then begin to fully open through the heating element. Or is the only adjustment just the heating element tension?

    • @MuscleCarSolutions
      @MuscleCarSolutions  Рік тому +1

      Your comment made me think if I should do another video on the choke mechanism and cover the vacuum source and the piston operation inside the choke body. Is it adjustable? No. But it made me think of a way to add a slight adjustment to it. Don’t think it would be possible, but something to tear into sometime.

      @@MuscleCarSolutions to me it gives you the benefit of being able to cold start with 100% closed choke, this almost gaurentees instant/easy starts (even with a very lean mix). Its probably more of a benefit at colder temperatures (i live in South Dakota). But its nice to have the failsafe of at least a partially opened choke incase the element, or your power source is incorrectly operating. The latter scenario probably being more rare.

      Start eliminating possible issues. SAFELY Disconnect the fuel line from our side of the fuel pump and crank to see you’re getting a lot of fuel. If you’re getting a ton of fuel, then hook up the regulator but disconnect the carb and make sure the fuel is flowing through the regulator. Next pop the top off the carb and inspect the needle and seats, float height, no garbage in the bowls. Once you have eliminated the fuel system, then move on to the ignition. All basic troubleshooting. Eventually you’ll find the issue(s).
